Magic Lantern was first reported in the media by of on 20 November 2001 and by Ted Bridis of the. The FBI intends to deploy Magic Lantern in the form of an.

When the attachment is opened, it installs a on the suspect's computer. The trojan horse is activated when the suspect uses encryption, often used to increase the security of sent e-mail messages.

When activated, the trojan horse will log the PGP password, which allows the FBI to decrypt user communications. Symantec and other major antivirus vendors have whitelisted Magic Lantern, rendering their antivirus products, including Norton Internet Security, incapable of detecting Magic Lantern. Concerns include uncertainties about Magic Lantern's full potential and whether hackers could subvert it for purposes outside the jurisdiction of the law.Graham Cluley, a technology consultant from, said 'We have no way of knowing if it was written by the FBI, and even if we did, we wouldn’t know whether it was being used by the FBI or if it had been commandeered by a third party'. Another reaction came from Marc Maiffret, and cofounder of, 'Our customers are paying us for a service, to protect them from all forms of malicious code.

It is not up to us to do law enforcement's job for them so we do not, and will not, make any exceptions for law enforcement malware or other tools.' FBI spokesman Paul Bresson, in response if Magic Lantern needed a court order to deploy, 'Like all technology projects or tools deployed by the FBI it would be used pursuant to the appropriate legal process.' Proponents of Magic Lantern argue the technology would allow law enforcement to efficiently and quickly decrypt messages protected by encryption schemes. Implementing Magic Lantern does not require physical access to a suspect's computer, unlike, a predecessor to Magic Lantern, since physical access to a computer would require a court order. Performance impact In 2006, Oli Warner published two articles comparing the system performance impact of various Windows applications, including.

He later reran the experiments, revising his methodology and included at Symantec's request.Warner benchmarked the processor and the disk performance with and without each application, compiling two scripts in, a. One calculated all between 100,000 and 200,000 and the other tested file read/write time. Was used to measure boot time. All testing was conducted inside a environment created. Despite the 2007 version's improvements, Warner noted its significant boot delay and impact on file operations.Recent testing conducted by PassMark Software found the 2009 version had the least impact on system performance. As noted earlier, Symantec funded the testing and provided some of the scripts used. Warner's scripts were also used to test file read/write time.

The second and third ranked suites were and, respectively. Systems were benchmarked with a clean installation of Windows Vista, then again with a security suite installed. The 2009 version had the least impact on boot time, the fastest scan speed, lowest memory utilization, and the program itself installed the fastest out of its competitors. However, the 2009 version had the second most impact on file read/write time, as highlighted by Warner earlier. Uninstallation Norton Internet Security (Windows versions) have been criticized for refusing to uninstall completely, leaving unnecessary files behind.

Versions prior to 2009 installed a separate program, which updates Norton-branded software. The user must uninstall both Norton Internet Security and the LiveUpdate component manually. The LiveUpdate component is purposely left behind to update other Norton-branded products, if present.

Cole also said that Symantec had done 'extensive testing' of its products with Windows XP SP3, but this issue had not surfaced. Cole essentially blamed Microsoft, 'This is related to XP SP3,' he stated. Microsoft recommended users to contact Windows customer support.

To resolve the problem, Symantec has issued a fix intended for users before upgrading. Symantec also recommends disabling the tamper protection component in the 2008 release, dubbed SymProtect. A tool to remove the added registry entries is also available from Symantec. Windows Vista Sarah Hicks, Symantec's vice president of consumer product management, voiced concern over Windows Vista 64-bit's feature. PatchGuard was designed by Microsoft to ensure the integrity of the, a part of a which interacts with the hardware. Often hide in a operating system's kernel, complicating removal.

Mike Dalton, European president of said, 'The decision to build a wall around the kernel with the assumption it can't be breached is ridiculous', claiming Microsoft was preventing security vendors from effectively protecting the kernel while promoting its own security product,. Hicks said Symantec did not mind the competition from OneCare. Symantec later published a white paper detailing PatchGuard with instructions to obtain a PatchGuard exploit.

After negotiations and investigations from antitrust regulators, Microsoft decided to allow security vendors access to the kernel by creating special instructions. References.
